Definitions
- the present patent application refers to a method of making a ready-to-use catheter assembly and to a ready-to-use catheter assembly.
- Such ready-to-use catheter assemblies are usually used for intermittent catheterization by persons who are able to do so without the assistance of a healthcare professional.
- An important feature of such catheters is the ability of the catheter to slide easily through the urethra without exposing the urethral walls to any risk of damage. Therefore, lubricated catheters are known which utilize a gel that is applied to the outer surface of the catheter tube prior to insertion into the urethra.
- hydrophilic coated catheters are known wherein a hydrophilic coating on the catheter tube is activated prior to use by means of a wetting fluid, for example, water or saline solution.
- the catheter assembly In order to reduce the risk of infection when performing intermittent catheterization of the bladder, the catheter assembly needs to be as clean and antiseptic as possible. Therefore, the catheter assembly is sterilized before use.
- a typical method used for sterilization of catheter assemblies is radiation sterilization.
- the water produces radicals which often induce unwanted changes within the material.
- the coating performance is often reduced, i.e. lubricity and dry out time of the catheter assembly are negatively affected. This effect on performance results from the reduction in coating constituents' molecular weight and / or through additional cross-linking of the coating.
- EP 2 060 296 A1 already shows a ready-to-use catheter assembly wherein an activated catheter is provided in a catheter package.
- the catheter assembly comprises a catheter package which is divided into a first cavity and a second cavity by a gas permeable, liquid impermeable barrier.
- the first cavity accommodates a hydrophilic coated catheter
- the second cavity accommodates a quantity of wetting liquid in its liquid phase.
- the catheter assembly is sterilized shortly after placing the catheter and the wetting liquid in the package.
- the liquid in the second cavity changes phase into vapor, the vapor passes the gas permeable barrier between the liquid and the hydrophilic coated catheter and activates the hydrophilic coating of the catheter.
- the time needed for activating the catheter is relatively long and may amount to 6 weeks.
- Another ready-to-use catheter assembly is known from Document US 2001/0001443 A1 .
- This document shows a ready-to-use catheter assembly comprising a urinary catheter with a hydrophilic coating and a catheter package with a cavity for accommodation of the catheter.
- the catheter package is made up of a gas impermeable material and accommodates a wetting liquid for activating the hydrophilic coating of the catheter.
- the wetting liquid is preferably contained in a spongy material.
- WO 03/092779 A1 discloses: a method of making and preparing for use a catheter assembly comprising the following steps: placing a catheter with a hydrophilic coating and a wetting fluid in a catheter package made of a material with low moisture transmission while the catheter package is in a first condition wherein at least an insertable length of the hydrophilic coating of the catheter is not in contact with the wetting fluid; sterilizing the catheter package with the catheter and the wetting fluid by means of radiation sterilization while the catheter package is kept in a condition in which at least the insertable length of the hydrophilic coating of the catheter is not in contact with the wetting fluid; and transferring the catheter package with the catheter and the wetting fluid into a second condition, thereby bringing the wetting fluid into contact with at least the insertable length of the hydrophilic coating of the catheter and activating at least the insertable length of the hydrophilic coating of the catheter.
- WO 03/092779 A1 further discloses: a catheter assembly with a catheter package made of a material with low moisture transmission and a catheter arranged in the catheter package, the catheter comprising an activated hydrophilic coating which is activated by a wetting fluid, the catheter package having two regions, which are designed so as to store the wetting fluid and at least an insertable length of the hydrophilic coating of the catheter separated from each other in a first condition of the catheter package, to bring the catheter and the wetting fluid together in a second condition and to allow free flow communication between the first region and the second region in the second condition.
- the method therefore comprises the following steps:
- the term “gravity” also comprises artificially induced forces, i.e. centrifugal forces.
- Low moisture transmission means that the material of the catheter package keeps the wetting fluid in the catheter package for at least the shelf life of the ready-to-use catheter assembly, so that the catheter remains activated for the complete shelf life.
- the shelf life lies in a range of 36 month to 5 years.
- the hydrophilic coating of the catheter and the wetting fluid are kept separate, so that any degradation of the quality of the hydrophilic coating and therewith of the lubricity of the ready-to-use catheter is avoided. Furthermore, as the activation of the catheter is carried out in a short time, it is not necessary to allow the aging of the catheter before use.
- the catheter and the wetting fluid are arranged in the catheter package in such a way that there is free flow communication between the catheter and the wetting fluid in the first and in the second condition. Therefore, when changing the condition of the catheter package from the first condition to the second condition, the wetting fluid can flow to the hydrophilic coating of the catheter without being disturbed by any obstacles. An easy activation of the catheter is guaranteed.
- activating the hydrophilic coating of the catheter is performed after sterilizing the catheter assembly and before shipment to the end-user.
- the activation of the catheter therefore is part of the manufacturing process of the ready-to-use catheter assembly, the catheter assembly is delivered to the user in a ready-to-use form, the user must not activate the catheter but can use it immediately.
- At least the insertable length of the hydrophilic coating of the catheter and the wetting fluid are separated via the force of gravity when in the first condition.
- This is a very simple method to obtain a secure separation between at least the insertable length of the hydrophilic coating of the catheter and the wetting fluid, which ensures that the hydrophilic coating is not damaged during radiation sterilization.
- at least the insertable length of the hydrophilic coating of the catheter is activated by turning the package with the wetting fluid and the catheter with the hydrophilic coating around an angle of at least 90°. This is a very simple way to bring the wetting fluid into contact with the hydrophilic coating of the catheter and thereby activating the hydrophilic coating of the catheter.
- a compartment for the wetting fluid is arranged in the catheter package which is in direct fluid communication with the hydrophilic coating of the catheter. It is thereby ensured that the wetting fluid is not accidentally brought into contact with a hydrophilic coating before the radiation sterilization of the catheter assembly.
- At least the hydrophilic coating of the catheter is surrounded by a sleeve which is combined with the compartment for the wetting fluid and directs the wetting fluid from the compartment to the hydrophilic coating.
- a sleeve which is combined with the compartment for the wetting fluid and directs the wetting fluid from the compartment to the hydrophilic coating.
- a ready-to-use catheter assembly comprising a catheter package made of a material with low moisture transmission and a catheter with an activated hydrophilic coating, the coating being activated by a wetting fluid, the catheter being arranged in the package, wherein the package has two regions which are designed so as to store the wetting fluid and at least an insertable length of the hydrophilic coating of the catheter separated from each other in a first condition of the catheter package, to bring the wetting fluid and the hydrophilic coating of the catheter together in a second condition and to allow free flow communication between the first region and the second region through changing over from the first condition into the second condition via gravity and / or inertia only.
- catheter assemblies which comprise a catheter package, a hydrophilic coated catheter and a sachet with wetting fluid, wherein the catheter and the sachet with the wetting fluid are arranged in the catheter package.
- a pressure is exerted on the sachet so that the sachet bursts open and the wetting fluid is delivered in the catheter package.
- the force which is necessary to open the sachet and to activate the hydrophilic coating of the catheter is a compressive force.
- the first region of the catheter package is formed by a compartment for the wetting fluid which is connected to the second region of the catheter package via a free flow opening.
- the compartment for the wetting fluid is separated from the second region of the catheter package via a bridge which comprises the free flow opening.
- the bridge can be easily realized for example as a welding seam in the catheter package so that an easy manufacturing of the catheter assembly is possible.
- the compartment for the wetting fluid has a tube-like shape and is arranged near a tip of the hydrophilic coated catheter. The wetting fluid is then directed to the catheter when activating the hydrophilic part of the catheter which helps in reducing the amount of wetting fluid needed.
- the amount of wetting fluid needed can further be reduced when the catheter is surrounded by a sleeve which is combined with the free flow opening of the tube-like shaped compartment and which sleeve directs the wetting fluid to the hydrophilic coating of the catheter when the assembly is in the second condition, in which at least the insertable length of the hydrophilic coating of the catheter is activated.
- the sleeve can comprise an insertion aid which is combined with the tube-like shaped compartment. This construction also helps in reducing the amount of wetting fluid needed.
- FIG. 1a shows a first embodiment of a ready-to-use catheter assembly 1.
- the ready-to-use catheter assembly 1 comprises a catheter package 2, a catheter 3 arranged in the catheter package 2 and a wetting fluid 4 which is also arranged in the catheter package 2.
- the catheter package 2 is made of a material that has a low moisture transmission such that the wetting fluid 4 is retained within the package 2. Examples for such materials with low moisture transmission are multi-layered polymeric films and aluminum foils. Due to the use of these materials, the wetting fluid is retained within the package for a time span of up to five years and typically 36 months. It is thus ensured that the ready-to-use catheter assembly has a suitable product shelf life.
- the amount of wetting fluid 4 needed can be minimized, because nearly no wetting fluid can escape from the package. As there is only a small amount of wetting fluid in the package, the risk of spillage when opening the package is reduced.
- the catheter package 2 comprises a bridge 7 which separates the lower part, the first region of the catheter package 2, from the remaining part of the catheter package 2, the second region, and forms a compartment 8 for the wetting fluid 4.
- the bridge 7 does not completely separate the first region, that is the compartment 8, from the second region of the catheter package 2 but comprises a free flow opening 9. Due to this free flow opening 9, a free flow communication between the catheter 3 and the wetting fluid 4 is realized in the package 2.
- the bridge 7 can for example be formed by a welding seam.
- Figure 1a shows the catheter assembly 1 in a first condition, wherein the compartment 8 with the wetting fluid 4 is arranged beneath the catheter 3.
- the different conditions of the catheter assembly 1 correspond to different positions of the catheter assembly 1. Therefore, the wetting fluid 4 is kept in the first region of the package via gravity and a secure separation between the hydrophilic coating of the catheter 3 and the wetting fluid 4 is realized. Therefore, when sterilizing the ready-to-use catheter assembly in this first condition, i.e. the first position, a contact between the wetting fluid 4 and the catheter 3 is avoided and any degradation of the hydrophilic coating of the catheter 3 is prevented.
- FIG. 2 shows a second embodiment of a ready-to-use catheter assembly 1'.
- This catheter assembly 1' basically corresponds to the catheter assembly as already described.
- the same reference numbers are used. In the following, the differences are described.
- the wetting fluid 4 is arranged in the compartment 8' and is therefore kept separate from the catheter 3 and the hydrophilic coating of the catheter 3.
- the end of the compartment 8' is open, so that the wetting fluid 4 is in free flow communication with the catheter 3. Therefore, the open end of the compartment 8' also forms a free flow opening 9'.
- the different conditions of the catheter assembly 1' correspond to different positions.
- the catheter 3 also comprises a catheter tube 5 and a catheter funnel 6. Near the tip of the catheter tube, the catheter tube 5 is provided with drainage eyes. At least parts of the catheter tube 5 are coated with a hydrophilic coating.
- the catheter tube 5 is surrounded by a sleeve 14. The sleeve 14 completely covers the catheter tube 5 so that the catheter tube 5 is not touched by a user when inserting the catheter in the urethra and the catheter is therefore kept antiseptic.
- an insertion aid 15 is connected to the sleeve 14. This insertion aid 15 facilitates the insertion of the catheter tube 5 in the urethra of a user.
- the insertion aid 15 has the form of a short tube. The inner diameter of the insertion aid 15 is larger than the outer diameter of the leg of the T shaped element 10. The insertion aid 15 is slipped onto the leg 13 of the T shaped element 10 and therefore surrounds the compartment 8' for the wetting fluid 4.
- the ready-to-use catheter assembly 1 is shown in a first condition, i.e. a first position of the catheter package 2.
- a first condition i.e. a first position of the catheter package 2.
- the wetting fluid 4 is arranged at the bottom of the catheter package, the first region, and the catheter 3 with the hydrophilic coating is arranged above the wetting fluid 4. Therefore, the hydrophilic coating of the catheter 3 does not come into contact with the wetting fluid 4.
- the ready-to-use catheter assembly 1 is then sterilized via radiation sterilization, for example, by means of gamma radiation while keeping the catheter package 2 in a condition, i.e. a position, in which the hydrophilic coating of the catheter 3 and the wetting fluid 4 are separated from each other.
- the ready-to-use catheter assembly 1 is rotated as can be seen in Figures 1b, 1c, 1d and 1e .
- the catheter package 2 is turned and brought in a second condition so that the compartment with the wetting fluid is arranged above the catheter 3. Due to gravity, the wetting fluid 4 changes its position in the compartment 8 and reaches the free flow opening 9. The wetting fluid 4 then flows through the free flow opening 9 of the bridge 7 and comes into contact with the catheter 3. Thereby, the hydrophilic coating of the catheter 3 is activated.
- Figure 2 shows the ready-to-use catheter assembly 1' in the first condition, i.e. first position of the catheter package 2'.
- the catheter package 2' In the first position, the catheter package 2' is arranged in such a way that the wetting fluid 4 is kept in the compartment 8' and is arranged below the catheter 3 with the hydrophilic coating.
- the catheter 3 and its hydrophilic coating are kept separate from the wetting fluid 4 via gravity. This position is maintained during the radiation sterilization of the ready-to-use catheter assembly 1'.
- the sterilization is preferably carried out with gamma radiation.
- Figure 3 shows the step of activating the ready-to-use catheter assembly 1'.
- the catheter package 2' is turned around an angle of at least 90°, and brought in a second condition, i.e. a second position so that the wetting fluid 4 flows from the compartment 8' through the introduction aid 15 into the sleeve 14 surrounding the catheter 3.
- the wetting fluid 4 is thereby brought into contact with at least the insertable length of the hydrophilic coating of the catheter 3 and activates at least the insertable length of the hydrophilic coating.
- the wetting fluid 4 is preferably a saline solution or water. Due to the use of the sleeve 14 which surrounds the catheter 3, only a small amount of wetting fluid is needed for activating the hydrophilic coating of the catheter. Due to this small amount of wetting fluid 4, nearly no free wetting fluid is left in the catheter package 2' after the activation of the catheter 3. Therefore, the risk of spillage when opening the catheter package 2' is minimized.
- the catheter After the activation of the hydrophilic coating of the catheter 3 with the wetting fluid 4, the catheter is in the ready-to-use condition. This means, that the whole catheter assembly 1' is delivered to the user in such a form that it can be directly used.
- the user does not have to undertake any steps to activate the catheter 3 but only has to open the package 2 to pull the activated catheter 3 with the sleeve 14 and the insertion aid 15 from the catheter package 2' and can start with the intermittent catheterization.
- the catheter package 2' is preferably provided with an opening 16 which can be easily opened and through which the user can pull out the activated catheter 3.
- the sleeve 14 remains on the catheter 3 when taking the catheter 3 out of the package 2'. The user then only touches the sleeve 14, the catheter 3, especially the catheter tube 5 which is inserted in the urethra of the user, is kept in an antiseptic state.
- the orientation of the catheter package 2, 2' from packaging to product release can be monitored using tiled indicators. In this way, it can be tracked if the process for making the ready-to-use catheter assembly has been executed without errors.
- the catheter package 2' is turned back in an upright position before pulling out the catheter 3. Excess wetting fluid can then return to the compartment 8' when the user takes the ready-to-use catheter assembly to open it. This helps to reduce the likelihood of spilling wetting fluid during the opening of the catheter package 2 and product use.
- wetting fluid can be directly loaded into the catheter package without providing a bridge or a compartment.
- the transfer of the wetting agent may also be via the catheter inner lumen.
- the catheter funnel and catheter drainage eyes may be used as the bridge for the wetting agent.
- the wetting fluid may also be included within a chamber in the catheter, and the catheter inner lumen or an insertion or handling aid.
- centrifugal forces may also be employed to ensure that the wetting fluid is transferred to the hydrophilic coated parts of the catheter.
- sudden linear displacement of a product can also be used to transfer the wetting fluid to the hydrophilic coating of the catheter.
- the inertia of the wetting fluid will resist the change in motion and stay stationary relative to the product.
- the wetting fluid will again resist this change in motion in its own state of motion (keeps flowing).
- the catheter assembly is delivered to the end user in a ready-to-use condition.
- the activation of the hydrophilic coating of the catheter is part of the method of making the ready-to-use catheter assembly. Therefore, activation of the hydrophilic coated parts of the catheter is performed at any time between sterilization of the catheter assembly and shipment to the end-user.
- the catheter package 2, 2' is made of a material with low moisture transmission, for example, multilayer polymeric films or aluminum foils. Therefore, the wetting fluid is retained within the package for a time span of up to five years and typically 36 months. It is thus ensured that the ready-to-use catheter assembly has a suitable product shelf life.

WO 03/092779 A1 WO 03/092779 A1 - It is the object of the present patent application to provide a further method of making a ready-to-use catheter assembly and to provide a ready-to-use catheter assembly which overcomes at least partially the disadvantages of the devices known so far.

- Transferring the catheter package with the catheter and the wetting fluid into a second condition, thereby bringing the wetting fluid into contact with at least the insertable length of the hydrophilic coating of the catheter, and activating at least the insertable length of the hydrophilic coating of the catheter via gravity and / or inertia.
- In the context of this document, the term "gravity" also comprises artificially induced forces, i.e. centrifugal forces. Low moisture transmission means that the material of the catheter package keeps the wetting fluid in the catheter package for at least the shelf life of the ready-to-use catheter assembly, so that the catheter remains activated for the complete shelf life. Usually the shelf life lies in a range of 36 month to 5 years.
- During radiation sterilization, the hydrophilic coating of the catheter and the wetting fluid are kept separate, so that any degradation of the quality of the hydrophilic coating and therewith of the lubricity of the ready-to-use catheter is avoided. Furthermore, as the activation of the catheter is carried out in a short time, it is not necessary to allow the aging of the catheter before use.
- According to the invention, the catheter and the wetting fluid are arranged in the catheter package in such a way that there is free flow communication between the catheter and the wetting fluid in the first and in the second condition. Therefore, when changing the condition of the catheter package from the first condition to the second condition, the wetting fluid can flow to the hydrophilic coating of the catheter without being disturbed by any obstacles. An easy activation of the catheter is guaranteed.
- In a further preferred variant, activating the hydrophilic coating of the catheter is performed after sterilizing the catheter assembly and before shipment to the end-user. The activation of the catheter therefore is part of the manufacturing process of the ready-to-use catheter assembly, the catheter assembly is delivered to the user in a ready-to-use form, the user must not activate the catheter but can use it immediately.
- In yet another variant of the method, at least the insertable length of the hydrophilic coating of the catheter and the wetting fluid are separated via the force of gravity when in the first condition. This is a very simple method to obtain a secure separation between at least the insertable length of the hydrophilic coating of the catheter and the wetting fluid, which ensures that the hydrophilic coating is not damaged during radiation sterilization. Furthermore, it can be provided that at least the insertable length of the hydrophilic coating of the catheter is activated by turning the package with the wetting fluid and the catheter with the hydrophilic coating around an angle of at least 90°. This is a very simple way to bring the wetting fluid into contact with the hydrophilic coating of the catheter and thereby activating the hydrophilic coating of the catheter.
- In still another variant of the method, a compartment for the wetting fluid is arranged in the catheter package which is in direct fluid communication with the hydrophilic coating of the catheter. It is thereby ensured that the wetting fluid is not accidentally brought into contact with a hydrophilic coating before the radiation sterilization of the catheter assembly.
- In still another variant of the method, at least the hydrophilic coating of the catheter is surrounded by a sleeve which is combined with the compartment for the wetting fluid and directs the wetting fluid from the compartment to the hydrophilic coating. In this case, only a very small amount of wetting fluid is needed for activating the catheter because it is directly led to the hydrophilic coated part of the catheter. There is no superfluous liquid in the catheter package which may spill when the package is opened.
- In case of the ready-to-use catheter assembly, the above mentioned object is solved by a ready-to-use catheter assembly comprising a catheter package made of a material with low moisture transmission and a catheter with an activated hydrophilic coating, the coating being activated by a wetting fluid, the catheter being arranged in the package, wherein the package has two regions which are designed so as to store the wetting fluid and at least an insertable length of the hydrophilic coating of the catheter separated from each other in a first condition of the catheter package, to bring the wetting fluid and the hydrophilic coating of the catheter together in a second condition and to allow free flow communication between the first region and the second region through changing over from the first condition into the second condition via gravity and / or inertia only. Due to this construction of the ready-to-use catheter assembly, it is possible to provide a catheter in a ready-to-use form which does not have to be activated by a user and which does not experience any degradation during radiation sterilization. So far, catheter assemblies are known which comprise a catheter package, a hydrophilic coated catheter and a sachet with wetting fluid, wherein the catheter and the sachet with the wetting fluid are arranged in the catheter package. In order to activate the hydrophilic coating of the catheter, a pressure is exerted on the sachet so that the sachet bursts open and the wetting fluid is delivered in the catheter package. As shown above, the force which is necessary to open the sachet and to activate the hydrophilic coating of the catheter is a compressive force.
- According to the invention, the first region of the catheter package is formed by a compartment for the wetting fluid which is connected to the second region of the catheter package via a free flow opening. With this construction, a free flow communication between the wetting fluid and the hydrophilic coating of the catheter for activating the catheter is possible, however, the risk of spillage of the wetting fluid before sterilization of the catheter assembly is minimized.
- It can further be provided that the compartment for the wetting fluid is separated from the second region of the catheter package via a bridge which comprises the free flow opening. The bridge can be easily realized for example as a welding seam in the catheter package so that an easy manufacturing of the catheter assembly is possible.
- However, it can also be provided that the compartment for the wetting fluid has a tube-like shape and is arranged near a tip of the hydrophilic coated catheter. The wetting fluid is then directed to the catheter when activating the hydrophilic part of the catheter which helps in reducing the amount of wetting fluid needed.
- The amount of wetting fluid needed can further be reduced when the catheter is surrounded by a sleeve which is combined with the free flow opening of the tube-like shaped compartment and which sleeve directs the wetting fluid to the hydrophilic coating of the catheter when the assembly is in the second condition, in which at least the insertable length of the hydrophilic coating of the catheter is activated.
- In yet another embodiment, the sleeve can comprise an insertion aid which is combined with the tube-like shaped compartment. This construction also helps in reducing the amount of wetting fluid needed.
- In the following the invention is described in more detail with the aid of drawings.

Figure 4 shows the ready-to-use catheter assembly ofFigure 2 shortly before use. -
Figure 1a shows a first embodiment of a ready-to-use catheter assembly 1. The ready-to-use catheter assembly 1 comprises acatheter package 2, acatheter 3 arranged in thecatheter package 2 and a wettingfluid 4 which is also arranged in thecatheter package 2. Thecatheter package 2 is made of a material that has a low moisture transmission such that the wettingfluid 4 is retained within thepackage 2. Examples for such materials with low moisture transmission are multi-layered polymeric films and aluminum foils. Due to the use of these materials, the wetting fluid is retained within the package for a time span of up to five years and typically 36 months. It is thus ensured that the ready-to-use catheter assembly has a suitable product shelf life. Furthermore, due to the very low moisture transmission of the package material, the amount of wettingfluid 4 needed can be minimized, because nearly no wetting fluid can escape from the package. As there is only a small amount of wetting fluid in the package, the risk of spillage when opening the package is reduced. - The
catheter 3 comprises acatheter tube 5 and acatheter funnel 6. The ready-to-use catheter assembly 1 is preferably used for intermittent catheterization. In order to allow an easy catheterization, the surface of thecatheter tube 5 which is inserted in the urethra, this is the insertable length, should have a high lubricity. Therefore, at least a part of thecatheter tube 5 is coated with a hydrophilic coating. In the context of this document the hydrophilic coated parts of the catheter are referred to as hydrophilic coating. The hydrophilic coating of thecatheter 3, that means thecatheter tube 5, must be activated before use to ensure the high lubricity of thecatheter tube 5. The activation is carried out by bringing thecatheter 3 and especially the hydrophilic coating thecatheter 3 in contact with the wettingfluid 4. - It is known that during radiation sterilization of the catheter assembly, the coating performance of an activated hydrophilic coating is reduced such that lubricity and dry out time are negatively affected. Therefore, the
catheter package 2 comprises abridge 7 which separates the lower part, the first region of thecatheter package 2, from the remaining part of thecatheter package 2, the second region, and forms acompartment 8 for the wettingfluid 4. Thebridge 7 does not completely separate the first region, that is thecompartment 8, from the second region of thecatheter package 2 but comprises afree flow opening 9. Due to this free flow opening 9, a free flow communication between thecatheter 3 and the wettingfluid 4 is realized in thepackage 2. Thebridge 7 can for example be formed by a welding seam. -
Figure 1a shows thecatheter assembly 1 in a first condition, wherein thecompartment 8 with the wettingfluid 4 is arranged beneath thecatheter 3. In this embodiment, the different conditions of thecatheter assembly 1 correspond to different positions of thecatheter assembly 1. Therefore, the wettingfluid 4 is kept in the first region of the package via gravity and a secure separation between the hydrophilic coating of thecatheter 3 and the wettingfluid 4 is realized. Therefore, when sterilizing the ready-to-use catheter assembly in this first condition, i.e. the first position, a contact between the wettingfluid 4 and thecatheter 3 is avoided and any degradation of the hydrophilic coating of thecatheter 3 is prevented. -
Figure 2 shows a second embodiment of a ready-to-use catheter assembly 1'. This catheter assembly 1' basically corresponds to the catheter assembly as already described. For the same parts, the same reference numbers are used. In the following, the differences are described. - The ready-to-use catheter assembly 1' also comprises a catheter package 2', a
catheter 3 which is arranged in the catheter package 2' and a wettingfluid 4, which is also arranged in the catheter package 2'. The catheter package 2' is made of a material with low moisture transmission as described above. Furthermore, anelement 10 is arranged in the package 2'. Theelement 10 has the shape of a T and is called T-piece. The two arms of the T are connected to the package 2' in order to fix theelement 10 in the package 2'. The leg of theT 13 is hollow and forms thecompartment 8' for the wettingfluid 4. InFigure 2 , the ready-to-use catheter assembly 1' is shown in a first condition which is maintained before and during sterilization. In this first condition, the wettingfluid 4 is arranged in thecompartment 8' and is therefore kept separate from thecatheter 3 and the hydrophilic coating of thecatheter 3. The end of thecompartment 8' is open, so that the wettingfluid 4 is in free flow communication with thecatheter 3. Therefore, the open end of thecompartment 8' also forms a free flow opening 9'. Also in this embodiment the different conditions of the catheter assembly 1' correspond to different positions. - The
catheter 3 also comprises acatheter tube 5 and acatheter funnel 6. Near the tip of the catheter tube, thecatheter tube 5 is provided with drainage eyes. At least parts of thecatheter tube 5 are coated with a hydrophilic coating. Thecatheter tube 5 is surrounded by asleeve 14. Thesleeve 14 completely covers thecatheter tube 5 so that thecatheter tube 5 is not touched by a user when inserting the catheter in the urethra and the catheter is therefore kept antiseptic. At the end of thesleeve 14 facing the tip of thecatheter tube 5, aninsertion aid 15 is connected to thesleeve 14. Thisinsertion aid 15 facilitates the insertion of thecatheter tube 5 in the urethra of a user. Theinsertion aid 15 has the form of a short tube. The inner diameter of theinsertion aid 15 is larger than the outer diameter of the leg of the T shapedelement 10. Theinsertion aid 15 is slipped onto theleg 13 of the T shapedelement 10 and therefore surrounds thecompartment 8' for the wettingfluid 4. - The package 2' is provided with a small bridge 7' which has an opening which surrounds the
compartment 8' and theinsertion aid 15 slipped onto thecompartment 8'. The bridge 7' helps in keeping the T shapedelement 10 in the right position. - In the following, the method for making the ready-to-use catheter assembly is described for the first embodiment of the ready-to-
use catheter assembly 1 with theFigures 1a to 1e . - In
Figure 1a , the ready-to-use catheter assembly 1 is shown in a first condition, i.e. a first position of thecatheter package 2. In this position, the wettingfluid 4 is arranged at the bottom of the catheter package, the first region, and thecatheter 3 with the hydrophilic coating is arranged above the wettingfluid 4. Therefore, the hydrophilic coating of thecatheter 3 does not come into contact with the wettingfluid 4. The ready-to-use catheter assembly 1 is then sterilized via radiation sterilization, for example, by means of gamma radiation while keeping thecatheter package 2 in a condition, i.e. a position, in which the hydrophilic coating of thecatheter 3 and the wettingfluid 4 are separated from each other. In this way, it can be ensured that the wettingfluid 4 does not come into contact with the hydrophilic coating of thecatheter 3 during the sterilization process of thecatheter assembly 1. A degradation of the hydrophilic coating of thecatheter 3 can thus be avoided. This position is maintained until radiation sterilization is completed. - After radiation sterilization is completed, the ready-to-
use catheter assembly 1 is rotated as can be seen inFigures 1b, 1c, 1d and 1e . When rotating the ready-to-use catheter assembly 1, thecatheter package 2 is turned and brought in a second condition so that the compartment with the wetting fluid is arranged above thecatheter 3. Due to gravity, the wettingfluid 4 changes its position in thecompartment 8 and reaches thefree flow opening 9. The wettingfluid 4 then flows through the free flow opening 9 of thebridge 7 and comes into contact with thecatheter 3. Thereby, the hydrophilic coating of thecatheter 3 is activated. As the activation of thecatheter 3, that means the hydrophilic coating of thecatheter 3, takes place after the radiation sterilization of the ready-to-use catheter assembly 1, a degradation of the hydrophilic coating of thecatheter 3 and thereby of the lubricity of thecatheter 3 is minimized. - In the following, the method of making a ready-to-use catheter assembly is explained with regard to the second embodiment for a ready-to-use catheter assembly 1' using
Figures 2 ,3 and4 . -
Figure 2 shows the ready-to-use catheter assembly 1' in the first condition, i.e. first position of the catheter package 2'. In the first position, the catheter package 2' is arranged in such a way that the wettingfluid 4 is kept in thecompartment 8' and is arranged below thecatheter 3 with the hydrophilic coating. Thecatheter 3 and its hydrophilic coating are kept separate from the wettingfluid 4 via gravity. This position is maintained during the radiation sterilization of the ready-to-use catheter assembly 1'. The sterilization is preferably carried out with gamma radiation. -
Figure 3 shows the step of activating the ready-to-use catheter assembly 1'. After sterilization, the catheter package 2' is turned around an angle of at least 90°, and brought in a second condition, i.e. a second position so that the wettingfluid 4 flows from thecompartment 8' through theintroduction aid 15 into thesleeve 14 surrounding thecatheter 3. The wettingfluid 4 is thereby brought into contact with at least the insertable length of the hydrophilic coating of thecatheter 3 and activates at least the insertable length of the hydrophilic coating. The wettingfluid 4 is preferably a saline solution or water. Due to the use of thesleeve 14 which surrounds thecatheter 3, only a small amount of wetting fluid is needed for activating the hydrophilic coating of the catheter. Due to this small amount of wettingfluid 4, nearly no free wetting fluid is left in the catheter package 2' after the activation of thecatheter 3. Therefore, the risk of spillage when opening the catheter package 2' is minimized. - After the activation of the hydrophilic coating of the
catheter 3 with the wettingfluid 4, the catheter is in the ready-to-use condition. This means, that the whole catheter assembly 1' is delivered to the user in such a form that it can be directly used. The user does not have to undertake any steps to activate thecatheter 3 but only has to open thepackage 2 to pull the activatedcatheter 3 with thesleeve 14 and theinsertion aid 15 from the catheter package 2' and can start with the intermittent catheterization. - This is shown in
Figure 4 . The catheter package 2' is preferably provided with anopening 16 which can be easily opened and through which the user can pull out the activatedcatheter 3. Thesleeve 14 remains on thecatheter 3 when taking thecatheter 3 out of the package 2'. The user then only touches thesleeve 14, thecatheter 3, especially thecatheter tube 5 which is inserted in the urethra of the user, is kept in an antiseptic state. - The orientation of the
catheter package 2, 2' from packaging to product release can be monitored using tiled indicators. In this way, it can be tracked if the process for making the ready-to-use catheter assembly has been executed without errors. As can be seen inFigure 4 of the second embodiment for the ready-to-use catheter assembly 1', the catheter package 2' is turned back in an upright position before pulling out thecatheter 3. Excess wetting fluid can then return to thecompartment 8' when the user takes the ready-to-use catheter assembly to open it. This helps to reduce the likelihood of spilling wetting fluid during the opening of thecatheter package 2 and product use. The same applies for thecatheter assembly 1 shown inFigures 1a to 1e . - Furthermore, it is pointed out that the wetting fluid can be directly loaded into the catheter package without providing a bridge or a compartment.
- The transfer of the wetting agent may also be via the catheter inner lumen. In this approach, the catheter funnel and catheter drainage eyes may be used as the bridge for the wetting agent. The wetting fluid may also be included within a chamber in the catheter, and the catheter inner lumen or an insertion or handling aid.
- In addition to gravity, the use of centrifugal forces may also be employed to ensure that the wetting fluid is transferred to the hydrophilic coated parts of the catheter. Furthermore, sudden linear displacement of a product (Newton's First Law of Motion) can also be used to transfer the wetting fluid to the hydrophilic coating of the catheter. The inertia of the wetting fluid will resist the change in motion and stay stationary relative to the product. When the product decelerates or stops suddenly, the wetting fluid will again resist this change in motion in its own state of motion (keeps flowing). This is a further mechanism of moving the wetting fluid from one place to another relative to the product and can act as a mechanism of activation based on inertia force of the wetting fluid and its resistance to change of motion.
- As already described above, the catheter assembly is delivered to the end user in a ready-to-use condition. This means, the activation of the hydrophilic coating of the catheter is part of the method of making the ready-to-use catheter assembly. Therefore, activation of the hydrophilic coated parts of the catheter is performed at any time between sterilization of the catheter assembly and shipment to the end-user.
- The
catheter package 2, 2' is made of a material with low moisture transmission, for example, multilayer polymeric films or aluminum foils. Therefore, the wetting fluid is retained within the package for a time span of up to five years and typically 36 months. It is thus ensured that the ready-to-use catheter assembly has a suitable product shelf life. -
